Donald Trump has suggested he would win in a fight against former vice-President Joe Biden.
In a tweet, the current US President said Barack Obama's former number 2 would "go down fast and hard, crying all the way".
Crazy Joe Biden is trying to act like a tough guy. Actually, he is weak, both mentally and physically, and yet he threatens me, for the second time, with physical assault. He doesn’t know me, but he would go down fast and hard, crying all the way. Don’t threaten people Joe!

It's in relation to comments Mr Biden made about Donald Trump's treatment of women at a sexual assault rally in Florida earlier this week.
Biden said: "If we were in high school, I'd take him behind the gym and beat the hell out of him."
The former VP made the comments when referring to an 'Access Hollywood' tape from 2005, where Trump spoke about grabbing women.
